England and Wales denied Arthritus drug but not Scotland

The N.I.C.E. team have not agreed to the drugs Tocilizumab or Roactemra in the UK, because it is Stg 9000 a year and NOT cost effective.
However, the Scottish people have agreed to it.
Forgive me for being sceptical, but how are they allowed to do this when the UK tax payer pays for it.
So if it's good enough for them why not us???
If they agree to it then make the Scottish tax payer pay for it ! - Oh yes I forgot not many of them have jobs and can pay tax!!!!
